LIDAR is cheap enough to put on a consumer car, so I really don't think expense is an issue. It wouldn't be GPS.
Not to mention the ships most likely already have transponders.
So it does seem like a "You're getting too close to the bank!" alarm should have been screaming at them. And probably was. Not responding properly was the issue.
- mbreese 3y agoHow far away does LIDAR work? These are huge ships, pretty far from the banks, and the required positions within the channel locations would vary heavily throughout the trip (and probably even change day to day). From the report though, you’re right that it seemed liked they already knew where they were in the canal with enough accuracy to know they were in trouble.
- aeonik 3y agoThey use Lidar to map jungles from airplanes, so the range can be pretty far. I'm not sure what the relationship between resolution and distance is though. I'd assume it's inverse square combined with the Raleigh criterion, or something like that. I'm going to have to research it more though. https://techcrunch.com/2022/05/27/lidar-exposes-the-remnants-of-an-overgrown-ancient-civilization-in-the-amazon/ https://techcrunch.com/2022/05/27/lidar-exposes-the-remnants...
